Secondly, fish farming in paddy fields is not convenient for fertilization and pesticide application. In the past, some farmers tried to raise fish in paddy fields. At that time, pesticides and fertilizers were rarely used, and all the fertilizers were farmyard manure, and there were few pesticides. Fish farming has indeed created conditions, but now it is different. Chemical fertilizers and pesticides are used for farming. However, it is more troublesome to raise fish in paddy fields when fertilizing and spraying drugs. If the dosage is not well controlled, the fish in paddy fields will be poisoned to death. And the dosage is less, and the pests and diseases of rice may be more serious. So it seems that raising fish in paddy fields is very simple, but it is more troublesome to operate. Maybe both rice and rice fish will reduce production seriously.
Once again, it is a technical problem. Farmers may have rich experience in planting rice, after all, they have been dealing with rice for a long time. But fish farming is a difficult problem for farmers. Most people have seen others raise fish but have no experience in this field, especially in rice fields, which is even more difficult. It is also because of the lack of technology that some people may have tried boldly before, but later failed, so they dare not continue. After other people realized the difficulty of raising fish in rice fields, they naturally gave up the idea considering that they didn't have the experience and technology in this field.
Of course, there is another reason. Fish can be raised in the paddy fields in the transit area. That's because there are many creatures in the paddy fields, all kinds of insects and aquatic plants, as well as many small fish and shrimps. Even if they are not fed with feed, the rice fish can eat some aquatic plants and aquatic organisms by themselves, and they grow very fat. But now the situation is different, because fertilizers, pesticides and herbicides are widely used, and many creatures in rice fields are gone. If rice fish are still cultivated in the traditional way, what will they eat? How to grow up? So it is also for these reasons that fish farming in rice fields is no longer suitable.
However, there is nothing wrong with the idea of cultivating rice fish in rice fields. At present, some remote mountainous areas still adopt this method, and a small number of rice fish are cultivated in some rice fields near the water source. When the rice is harvested, the rice fish also grow up. Moreover, this kind of rice fish grows naturally, without any feed, and the price in the market is not cheap. It can generally be sold for more than 30 yuan a catty, and it is still in short supply.
